Excellent design with some caveats in application.
After 3 months of use doing 12 hr prints in tropical climate the stepper motor was hot enough to make the PETG frame brittle. Swapped to a frame printed in polymide co-pa and no problems so far.
- The cooler fan duct don’t have enough clearance for original e3d silicon socks. Mine melted the duct so now I go without.
Now able to print with all of the advantages of direct drive. Lovely!
Btw Could you release the step files? I want to add a BLtouch and widen the fan duct clearance. Thanks
